Enum StreamMaxlen 

#[non_exhaustive]
pub enum StreamMaxlen {
    Equals(usize),
    Approx(usize),
}

Available on crate feature streams only.

Utility enum for passing MAXLEN [= or ~] [COUNT] arguments into StreamCommands. The enum value represents the count.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Equals(usize)

Match an exact count

Approx(usize)

Match an approximate count

Trait Implementations

impl Clone for StreamMaxlen

fn clone(&self) -> StreamMaxlen

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for StreamMaxlen

impl Debug for StreamMaxlen

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for StreamMaxlen

impl PartialEq for StreamMaxlen

fn eq(&self, other: &StreamMaxlen) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for StreamMaxlen

impl ToRedisArgs for StreamMaxlen

fn write_redis_args<W>(&self, out: &mut W)

where W: ?Sized + RedisWrite,

This writes the value into a vector of bytes. Each item is a single argument. Most items generate a single item.

fn to_redis_args(&self) -> Vec<Vec<u8>>

This converts the value into a vector of bytes. Each item is a single argument. Most items generate a vector of a single item.

fn describe_numeric_behavior(&self) -> NumericBehavior

Returns an information about the contained value with regards to it’s numeric behavior in a redis context. This is used in some high level concepts to switch between different implementations of redis functions (for instance INCR vs INCRBYFLOAT).

fn num_of_args(&self) -> usize

Returns the number of arguments this value will generate.
